Maxima Function
fasttimes (p_1, p_2)
Returns the product of the polynomials p_1 and p_2 by using a
special algorithm for multiplication of polynomials. p_1 and p_2 should be
multivariate, dense, and nearly the same size. Classical
multiplication is of order n_1 n_2 where
n_1 is the degree of p_1
and n_2 is the degree of p_2.
fasttimes is of order max (n_1, n_2)^1.585.
